Product Description
C# is Microsoft's hot new language for the .NET platform. This book covers everything C# programmers need to know to create network applications, a task traditionally done in C++. It explores the basics of network programming, including IP and TCP protocols, and moves on to targeted C# instruction, including using the C# network programming classes in the .NET framework. Topics covered include low-level network programming (such as sockets and multithreading), as well as network application layer programming for email, web-based, and security applications. Specific examples show how to create applications that use network protocols such as SNMP, SMTP, and HTTP. The book also has advanced coverage of incorporating an Active Directory server database and .NET remoting in a network application. Author Richard Blum has been a network and systems administrator for 13 years for the Department of Defense and is the author of four books on networking topics.

From the Back Cover
On its own, C# simplifies network programming. Combine it with the precise instruction found in C# Network Programming, and you'll find that building network applications is easier and quicker than ever.

This book helps newcomers get started with a look at the basics of network programming as they relate to C#, including the language's network classes, the Winsock interface, and DNS resolution. Spend as much time here as you need, then dig into the core topics of the network layer. You'll learn to make sockets connections via TCP and "connectionless" connections via UDP. You'll also discover just how much help C# gives you with some of your toughest chores, such as asynchronous socket programming, multithreading, and multicasting.

Network-layer techniques are just a means to an end, of course, and so this book keeps going, providing a series of detailed application-layer programming examples that show you how to work with real protocols and real network environments to build and implement a variety of applications. Use SNMP to manage network devices, SMTP to communicate with remote mail servers, and HTTP to Web-enable your applications. And use classes native to C# to query and modify Active Directory entries.

Rounding it all out is plenty of advanced coverage to push your C# network programming skills to the limit. For example, you'll learn two ways to share application methods across the network: using Web services and remoting. You'll also master the security features intrinsic to C# and .NET--features that stand to benefit all of your programming projects.
